Bought the house when we had one kid. Now we have four. It’s too small for us to live in right now. That said, we’re thinking when our older kids move out we’ll move back in to our first house. The mortgage is certainly cheaper.
After leaving that house we moved twice (into larger homes… my in-laws moved in with us at one point). We bought both times. We rent our residence now for a couple of reasons: COVID fucked up my finances from a few angles and we couldn’t get lending this time. And we’ve got 3 kids moving out in the next 3 years or less. So we’re kind of in a transition period anyway.
